A5 2017 battery replacement

[mhaxor]

Hi guys,

hope you can help me with the following.
I recently got an A5 2017 which wasn't used for 2 years.
Obviously the battery was dead, which was confirmed using a voltmeter.
I ordered a new one, tested it with the voltmeter and installed it in the phone.

When I plugged it to charge, after a few seconds I can see the charging animation showing up, it's at almost 85% now.

But I tried and cannot start the phone.
I tried many keys combinaison with no success, all I can have is the phone's charging animation.

I dismantled the whole phone and none of the liquid sensor seems triggered.
I removed both SIM trays and SD card as well, no luck.

Only while plugged in to a socket turns on the screen with charging percentage.
I tried to connect the phone to USB to my laptop and it doesn't do anything.

Any suggestion here?

Thanks

Whilst unplugged, press and hold the power button for literally a minute. Release. Wait 10 seconds. Press and hold power until turns on.

It may work.

It may not

Worth a try

Annnnnnnnnnnnnnnnnnnnnnnnnnnd it switched on, I don't know why nor how.
I put the back cover in place (the one above the battery, not the one of the phone itself) which in my opinion links the power button to the motherboard itself (but I may be wrong) and it switched on after just a few seconds pressing the power button alone.
Hope this helps someone else, anyway thanks a lot for your reply which is much appreciated.
